Poseidon Linux is designed for the international scientific community, bundling a big batch of science-oriented software into a single live DVD, plus a batch of desktop productivity and multimedia applications. Poseidon 4.0 was just released with significant changes, so let's take it for a test drive.
The Briny Deeps
Poseidon Linux is developed and maintained by scientists from the Rio Grande Federal University Foundation in Rio Grande do Sul, Brazil and other supporters all over the globe. It was named Poseidon because its development was driven by a school of oceanologists.
Poseidon was originally a derivative of Kurumin Linux. Kurumin is no more as it has been discontinued since 2008, but in its time it was a big deal that generated a lot of excitement and interest in Linux. Kurumin was a stripped-down Knoppix that fit on a mini-CD, with excellent hardware detection, a hard drive installation option (which the early Knoppix releases did not have), a beautiful appearance, and comprehensive documentation written in Brazilian Portuguese. Linux and FOSS are very popular in Brazil thanks to projects like Kurumin.
